Simple use of event bus

1. Import dependence

implementation 'org.greenrobot:eventbus:3.0.0'

2. Customize Event class

public class MyEvent {
    String message;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public MyEvent(String message) {
        this.message = message;
    }
}

3. Registering and unsubscribing

// Registration events 
EventBus.getDefault().register(MainActivity.this);


// Unregister event 
EventBus.getDefault().unregister(MainActivity.this);

4. Define how to handle events

@Subscribe(threadMode = ThreadMode.MAIN)
    public void handleEvent(MyEvent myEvent){
        textView.setText(myEvent.getMessage());
    }

5. Send events

EventBus.getDefault().post(new MyEvent(" Send custom events "));
